Figure 1 is a longitudinal section of a plunger showing a valve lifting and holding device embodying my invention; Fig. 2 is a perspective view of the lifting and holding device; and Fig. 3 is a section on the line 33 1. A tubular plunger, a valve therein, the lower portion of the plunger having an interior annular flange provided with opposite notches, and a valve lifting and holding device consisting of a length of resilient metal slidable through said notches, and having up per depressions for engaging with the flange,

The plunger comprises an upper section 5 and lower depressions for engaging with the and a lower section 6, which are secured to flange. gether by screw-threads, in the usual man- 2. A lifting and holding device for a well ner;- and attached to the plunger are leathers plunger valve, consisting of a strip of resilient metal having side members and a cross-member at the lower portion in said side members, each of said. side members having two inward depressions.
